Abstract

Abstract:

BACKGROUND: Porcelain veneer is a minimally invasive method for tooth aesthetics, but repairing effects of various porcelain veneers have yet to be compared.

OBJECTIVE: To compare the therapeutic effects of IPS e.max and VITA VM9 porcelain laminate veneers within 3 years．

METHODS: Thirty IPS e.max veneers were made for 22 patients (30 affected teeth) and 29 VITA VM9 porcelain laminate veneers were made for 28 patients (29 affected teeth). Three years after restoration, color match, surface texture, marginal discoloration, and marginal integrity of two veneer systems were clinically examined following modified CDA/Ryge criteria. Clinical success rates were compared between two groups and patient satisfaction was assessed by visual analog scale.

RESULTS AND CONCLUSION: Three years after restoration, there was one case of failure in the group of IPS e.max veneers, with the presence of gaps and dentin exposure, and one case of failure in the group of VITA VM9 porcelain laminate veneers, with the presence of insufficient margins and exposure of base materials. The success rate was 97% for both IPS e.max veneers and VITA VM9 porcelain laminate veneers, and there was no significant difference between the two kinds of veneers (P > 0.05). The patient satisfaction was scored as (86.38±7.83) points for IPS e.max veneers and (88.63±6.83) points for VITA VM9 porcelain laminate veneers, and no difference existed between the two kinds of veneers. To conclude, both IPS e.max and VITA VM9 porcelain laminate veneers are successful methods for veneer restorations．
